The 4000 was basically a Z4/Z8 with a sequencer no? Those were like extremely clean and crystal clear samplers. Pretty 'sterile' like my old S-2000 or an MPC, a predecessor to something like Kontakt maybe. They were awesome samplers, the computer integration was rad. But yeah, if you were like a drum and bass or hip-hop guy you still got an EMU, Ensoniq or an S950 instead for THAT sound.
